Hi Community,
Is it possible to append a branch to a transaction after the call is in a
ringing state? Say a call comes in and an AOR only has two contacts.
Branches are created to the contacts. A third comes in why the two are in
the ringing state. Can we create a branch to the third?

You can, but since Kamailio is driven by external events, you'd have to devise some
means of doing it.
The `tsilo` module is one popular way, but it is coupled to the registrar and doesn't
allow you to inject arbitrary branches at arbitrary times, so you may need to devise an
alternative.

It looks like TSILO ts_append is a good candidate for this.

As long as the destination you're wanting to do a deferred fork to is a new
registration contact, it fits like a glove. This is because ts_append() reads registration
contacts internally, "performing a contact lookup on the table specified by the
domain parameter" (from the ts_append() docs). The other functions are variations on
that same theme, with the same mechanism.
If you're wanting to do a deferred fork to arbitrary destinations, on the other hand,
you might be out of luck for the moment. I'm not aware of a way, beyond `tsilo`, to
side-load new branches into a pending transaction, though I'd be excited to find out
I'm wrong.
